		abstract={Wing in Ground Aircraft (WIG) is a flying boat with wings that is typically used
for short- distance flights such as inter-island transportation. Therefore, WIG
aircraft utilizes theprinciple of ground effect to be able to fly. Passengers will feel 
as if they are floating when flying. The working principle of the WIG aircraft at 
the time of flight seems to be "supported"by the air, often called an "air cushion."
The research was carried out in a 2D domain using a turbulent model of Large 
Eddy Simulations (LES). The turbulent flow on the LES model is depicted by 
eddies with long ranges and wide timescales. The largest vortices (large eddies)
are usually proportional in size to the average flow characteristics. In the LES 
model, large eddies will be completed directly, while small eddies will be
modelled.
The results of the simulation carried out on the NACA 2412 airfoil with the 
parameters of the angle of attack used were 0°, 4°, 8°, and 12°, as well as 
unbound, 0.1c, 0.4c, and 0.8c. Aerodynamic characteristics of NACA 2412 were 
obtained with the highest CL value at an angle of attack of 12 ° at the altitude of 
0.1 c and a CL value of 1.6557, while the highest CD value occurred at the attack 
angle of 12 ° at the unbound height with a CD value of 0.076322.The maximum
value of CL/CD was obtained at the AoA of 4° at altitude (h) 0.1c, with the CL/CD
value of 243.4327047. Therefore, it can be concluded that the height (h) can affect 
the aerodynamic characteristics of the airfoil.}
